## Abstract

The present application relates to wireless communications suitable for smart manufacturing and industrial automation. In particular, the application proposes a wireless communication device (UE) and a network device (BS), in particular suitable for cyclic communication. The BS is configured to provide a first information defining a hopping sequence to a UE, and to provide a second information to the UE defining when the hopping sequence should be repeated, in particular periodically repeated. The UE is accordingly configured to receive the first information from the BS, and to receive the second information from the BS. The hopping sequence specifies at least two spatial resources and/or at least two radio resources, which the UE is configured to use for transmissions to and/or from the BS.
